摘要
通过苏州城市环境地球化学调查工作的实施,对城市土壤环境地球化学研究的工作方法进行了初步研究。结果显示,苏州城市土壤的主要污染区域分布于东南居民生活区、西部工业区、东部木材加工厂集中区及公路干线一带;主要污染物为重金属、有机污染物多环芳烃、有机氯农药等。根据城市自然地理环境、功能分区特点和分布面积大小,确定土壤环境地球化学采样密度和测试项目是城市土壤环境地球化学研究的关键技术。
Preliminary study carried out on the methodology for the environmental geochemistry of Suzhou urban soils shows that the main contaminated zone is distributed in the residential area in the southeast, industrial area in the west and concentration area of timber processing factories in the east and along arterial highways. The main pollutants are heavy metals, persistent organic pollutants such as polycyclic aromatic hydrocarbons and organic chloride pesticides. The key methodology for urban soil environmental geochemical research is to determine the soil sampling density and items of analysis according to the physiographic environment, functional divisions and distribution area of the contaminated zone in the city.
